` SHEET-METAL DOOlh To alfwhom it may concern:

Be it known that I, NiLs P. SJOBRrNG, a

'citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Sheet- Metal Doors, of which the following is a specification. 1

This invention relates to certain new and useful improvements in sheet-metal doors, and the invention consists of the parts and the constructions, arrangements, and combinations of parts vwhich I willhereinafter describe and claim.

An essential object of the present invention is to devise a new and, efficient method of securing the rails of sheet-metal doors to the panels; to devise a simple and effective means for securing the glass slab or sheet in doors designed with glass panels, and to provide improved means .for securing sheetmetal anells to the rails ofdoors.

In t e accompanying drawings forming Vpart of this specification and in which simiar refei'ence characters indicate like parts in the several views 1,-.-Fi ure 1 is a side elevation of a door ernbo ying the salient feainvention. Fi 2 is an enlarged; `longitudinal sectiona view of the saine, on the line 2-2 of Fi 1. Fig. 3 is a cross-sectional view, on the lineB-S-of Fig. 1.' Fig. 4 is a cross-sectional view, on the line 4-4 of Fig; 1. Fig. 5 is asimilar section, on line 5-'5 of Fig. 1. Fig. 6 is a crosssectional view, on a line corresponding to -3-'-3 of Fig; l, but showing a modified construction. Fig. `7 is a bioken perspective "view showing more clearly the means for securingr a glass panel.

Fig. 8 is a broken persiective view of a portion of a bottom rail showing the manner of securing a sheetmetal panel. Fi 9 shows a modified means for securing a rai to a metal panel.

he general, design of the door shown is wellknown and follows more or less closely the door disclosed invmy former pat nts 847,443,Mar. 19, 1907 and'. 809,145, Jan. 2, 1906, in that it may be provided with`siinilar panels on opposite sides, and the side sections or Stiles may vbe integrally formed to present in onebody both sides of the doors.

The stiles are substantially identical in' construction, and a description of one will suffice for both.

Each of the Stiles, S is formed of a single I Specification of Letters Patent. Application filed February 1, 1908. Serial No. 413,796.

strip of metal of appropriate sha c in crossseetion andhaving a length equa to the dcsired height of the door, and each stile comprises parallel plates or strips 4 and 5, which are spaced apart a ,distance equal to the desired thickness of the door from front to rear, the inner edges 0f these plates or strips being inturned and fashioned with appropriately formed locking-flanges, 6, substantially as shown in my aforesaid former pat- When constructinol the door with a metal panel, as shown in the lower panel of Fig. 1 and in Figs. 2, 4 5, each panel-section,- is formed of a sheet-metal late, p, one for each side of the dooi, with said plates spaced apart a distance equal to the desired t 'ckness of the panel, and each late consists of a sheet or strip of suitable ength which near one edge is projected or offset, as at 7, and then inclined outwardly in either regular or irregular curve, as at 9, t0 form a molding portion interior to the inner edge of the side stilcs, the free ed e of this molding portion being bent inwar ly at right-angles to form a wall, 10, and thence again bent at right-angles and interlocking with the aforesaid locking fiang'e, 6, formed along the inner side edge of the` stile-section, this-construction being well shown in iny said former patents. The upper and lower rails or end sections of the door may be of identical construction, but when usin a glass panel, say in the upper part oi the door as in Figal, 2, 3 and 7, the means for securing this panel will be modified, as I will now explain. The' said rails or' upper and lower end sections of the door each comprise duplicate plates, `1:5, the outer edges of which are arranged to Loverlie and restin enagement with the intu'rned flanges, 12', orined on the edgesof the keeper, 12, to which flanges the said plates, 15, are bolted, riveted, or otherwise'seeurely fastened. `The plates, 15, have a length siiitablefor the desired width of door and the inner edges of said plates are inturned and fashioned with lockingiangles, 16, which substantially correspond to t ose before described as made on the inner' side edges ofthe stiles.

A When itis desired to construct the aforo(- said door, or one of equivalent form, witlia glass panel, as shown in Figs. 1, 2, and 3, I iorrn the molding portions which surround the panel, of separate ieces, 24 and 25, and it is to these features t at my present invenico iio

tion is particularly related. To better distinguish between the separate moldingpieccs, l will hereinafter re'l'er to the pieces 24 as the fixed molding-pieces and the pieces 2o as the loose molding-pieces although it Will beunderstood that the pieces 25 are loose only in the sense that they are the pieces which are insertible alter the glass slab 'o1-,panel is seated on-or against the other :ieces and after the ixed pieces are interocked with the locking-flanges on the stiles `and rails, or plates, 15, of the 'door'.

rDhe ixe'd molding-pieces, 24, have one edge 'fashioned to interlock with the aforesaid locking flanges, 6, 16 on the stiles and rails, or plates, 15, and they are each bent inwardly and then formed with some appropriate, regular or irregular, curve as shown at 19 to form a molding-portion Which terminates in a shoulder at 20. From this shoulder the ixedmolding-piece, 24, is 'bent backwardly to i'orm a Wall, 21, which is parallel with the iront and rear sides ol' the door and against which wall the ilat side ol' the glass slab or.

panel, P, is adapted to seat, as shown, in Fig.

2. At the outer end of the Wall, 21, the iixed ,llOlding-pieee is bent at right-angles, to form an Aend Wall, 22, toward the opposite side of vthe door, and thence is formed with an inclined wall or portion, 22, out of which or an and arrangement being substantially alike in both cases'. 'The companion molding-piece,

,namely the loose piece, 25, consists of a lsheet of metal which is bent to form a Wall, 30, Which standsparallel with the wall, 21', of the other piece, 24, the inner edge of said loose piece, 25, being bent at right angles to l'orni a tongue, 31, which lies upon and parallel with end Wall, 22, `of the molding-piece, 24, and ,is designed to slip under suitable tongues, struck out from the piece, 24, at or near the junction of the Wall, 21, thereof with the end Wall, 22, as clearly shown in Figs. 2 and 7 thus substantially interlocking one part With the other.

` TheJ freev end, or edge, of the loose molding-piece, 25, isbent at right angles from the end of the Wall, 30, and is thence fashioned With a curvedor other molding' portion, 33, which may be identical with the corresponding molding portion, 19, on the piece 24; and

fthe terminal free edge of the piece, 25, is formed With an.` inturned hook-shaped portion 34 adav ted to besprung into engagement with. t e struck-out inclined tongues,

26, of the fixed molding piece, 24, thereby docking the loose molding piece, 25, to the companion lixed 'molding` picco, 24, and,

pieces, 24 and 25, and presenting' a moldingfinish around the panel of a most attractive character.

In Fig. G, l illustrate a slight modification of the fore-going construction: In this ligure', the fixed molding-picar, 24, is oil'set at 24 to form a locking shoulder and the free or outer edge of the loose molding piece, 25, has a hook-shaped portion, 25, to interlock With said oliset or shoulder. Also, the iixed molding-piece is slightly offset, at 24h, at the base of the vertical Wall of the said fixed molding piece, and the bent portion or tongue, 25", of the loose molding piece engages with said oiset, as shown in said Fig. 6. ln other respects the panel of' Fig. 63's like the one before described for'Fig. 2.

As shown in Fig. 2, the lower panel of the i door may be eomposedof metal plates, y), spaced apart and With an intermediate lin .ing oi asbestos. These panel plates are secured to the bottom rail by .lirst slitting and then stamping out tongues, 40, beyond the outer facebf the panel-plates g and the molding portion of each bottom rail composed of the plates 4 5, has its inner edge bent to form a` hook-shaped portion, 41, which is-V Cil In this instance the metal sheets `forming the panel are slotted or provided with apertures, 42,'

and the inner'edge of the molding-section or piece, which may be integral With a rail, is provided with bent tongues, 43, which enter and interlock with the slots or apertures, 42, in the metal plates of the panel.

Frein the foregoing it. Will be seen that lV tongues, 32, at the baseof the wall, 21, ol the iixed piece, 24, and the free end lof said loose molding piece is sprung yover/or into engage- -ment With the tongues,^26, of said tixed molding-piece, when the loose piece, 25, is .locked to the companion, piece and secures imV Vie

the glass panel in place. By reason of the free or spring--end of the loose molding-piece, said piece is adjustable to any desired thickness of glass. Substantially the saine operation is carried out with the modified construction of Fig. 6 for in this casewhen the glass is inserted, the spring-eiid of the loose,

`as the latterI may be readily shoved into looking engagement with the outstanding tongues, Athus securing the parts without the use of screws, rivets, and like supplemental fasteniiigs.

Among the advantages of the present construction over the prior patented ones, is that by the method shown of fastening the bottom rail to a metal panel by the use of struck f tongues, I am permitted to dispense with t-he it O I ply to a panel'.

use of a separate angle molding, which re-' quires considerable time to make and to ap- By tl'i'e present method the molding-'portion of the rail is made at one and the same operation with the rail, by the use of appropriate dies, thereby saving mater'ial and time and making a construction which may be more easily applied.

The method of securing the glass panel has a distinct advantage over my prior patent inasmuch as the loose molding member is adjustable thereby enabling me to use glass oi diferent thickness, and said member forms a more substantial fastening than that of the former patent. The modifications shown in Fig. 4 is also of advantage because less stock is required and the loose moldingsection can be inserted behind the glass with less diliiculty also by this arrangement I can hold 1 glass firmly witho ut the use of putty, screws, cementy or rubber protected panels.

Having thus described my invention what I claim as new and desire to secure by Letters I Patent is l.
